Supergirl: Trinity

The fight with the World Killers is building to something truly impressive as we see in “Trinity.” After so many secrets were revealed last episode, Lena Luthor is being questioned by the DEO, especially Supergirl, Alex, and J’Onn.

Supergirl: Of Two Minds

Supergirl and company start off with a scene that will make you not want a cookie for a while. After that, they go back to following up on the dead birds that were raining down at the end of last episode.

Supergirl: Both Sides Now

Supergirl gets to her last episode before another long break in “Both Sides Now.” It starts with a major show of force as the Girl of Steel, the DEO, and Mon-El go to the suburbs to find Purity, the next of the world-killers.

Supergirl: For Good

Do you have any idea what my deductible is?

The Supergirl versus Reign story continues in “For Good,” which seems like an apt title for Supergirl in general. Kara is having strange visions of Reign and her fellow world-killers (such a cheery title) and goes in to the DEO to find no one has really made any progress.

Supergirl: Fort Rozz

Since the second half of this season seems to be focusing a great deal on Reign, they need to learn more about her. So it makes perfect sense that this episode would be about trying to gather some intel about her. But to do that, they need to revisit something that was important season one and has largely faded since then. Supergirl and company pay a visit to “Fort Rozz.”

Supergirl: Legion of Super Heroes

After a few weeks off for the winter break, Supergirl returns, and she’s not alone. Now, the Girl of Steel is allied with a version of one of DC Comics’ biggest and most powerful teams, which also gives us the episode title: “The Legion of Super Heroes.”
